Product Overview

Schizochytrium sp. is a marine microalgae cultivated as a primary source of DHA (docosahexaenoic acid), a polyunsaturated omega-3 fatty acid. The oleoresin offers a vegan alternative to fish oil and is used in food supplements, cosmetics, and animal feed [6, 7, 8, 9].

Typical applications: Schizochytrium sp. DHA Omega-3 Fatty Acid – Oleoresin

Functional Highlights

  • DHA contributes to the maintenance of normal brain function and vision [6, 7, 8, 9]
  • DHA contributes to the maintenance of normal heart function and cholesterol levels [6, 7, 8, 9]
  • Provides a vegan, fish-free source of DHA suitable for vegetarian and vegan nutrition [8]
  • Rich in polyunsaturated fatty acids; DHA content exceeds EPA content across species and production techniques [5]
  • Iodine content is minimal due to closed-system cultivation — unlike macroalgae, Schizochytrium does not accumulate iodine
  • In cosmetic applications, shows potential for deep hydration, anti-aging properties, pore-clearing, and improvement of skin discoloration [10, 11]
  • Shows anti-inflammatory properties relevant to cosmetic use [10, 11]

Production and Cultivation

Schizochytrium sp. is cultivated in closed systems, enabling continuous year-round production with full control over water quality and environmental parameters. The microalgae reacts strongly to changes in the culture medium and environmental conditions, which allows the fatty acid profile — including DHA content — to be actively controlled during cultivation.

Fermentation-based cultivation using sugars rather than sunlight enables higher productivity and concentrations compared to photobioreactor cultivation, while reducing water and energy consumption and minimizing environmental impact regardless of seasonal variation.

FAQ

What is Schizochytrium sp.?

Schizochytrium is a genus of marine microalgae found in marine habitats as well as brackish and saline waters. It is commercially cultivated as a primary source of DHA, a polyunsaturated omega-3 fatty acid.

What is DHA and why is it important?

DHA (docosahexaenoic acid) is an omega-3 fatty acid essential for normal brain function, vision, heart function, and cholesterol maintenance. It is also essential for the development of the brain and central nervous system in unborn and newborn humans and animals [6, 7, 8, 9].

What is the difference between Schizochytrium and Aurantiochytrium?

Both are microalgae genera commercially cultivated for DHA production. The primary difference lies in the quantity of DHA contained in each — they are distinct genera despite sharing similar industrial applications.

What is Schizochytrium sp. oleoresin used for?

It is used as a vegan DHA source in food supplements, fortified foods, cosmetics, and animal feed. It is suitable for vegetarian and vegan nutrition as an alternative to fish oil [8, 10].

How is Schizochytrium sp. cultivated?

It is cultivated in closed systems using fermentation-based methods. Environmental parameters are actively controlled to maximize DHA yield. This method enables year-round production while reducing water and energy use.

What DHA concentrations are available?

Two variants are available: DHA 400 mg and DHA 550 mg per gram. This gives manufacturers flexibility to select the appropriate concentration for their application.

Can Schizochytrium sp. be used in animal feed?

Yes, Schizochytrium sp. is suitable for use in horse feed and animal feed generally. It can be incorporated into solid feed formulations or used in the form of algae oil [10].

What are the cosmetic applications of Schizochytrium sp.?

In cosmetics and personal care, Schizochytrium sp. shows potential for deep hydration, anti-aging properties, pore-clearing, and improvement of skin discoloration. It is also valued for its anti-inflammatory properties [10, 11].
